BRAIN RULE RUNDOWN

Rule #1: Exercise boosts brain power.

The human brain evolved under conditions of almost constant motion.
From this, one might predict that the optimal environment for processing
information would include motion. That is exactly what one finds. Indeed,
the best business meeting would have everyone walking at about 1.8 miles per
hour.

Researchers studied two elderly populations that had led different lifestyles,
one sedentary and one active. Cognitive scores were profoundly influenced.
Exercise positively affected executive function, spatial tasks, reaction times
and quantitative skills.

So researchers asked: If the sedentary populations become active, will their
cognitive scores go up? Yes, it turns out, if the exercise is aerobic. In four
months, executive functions vastly improve; longer, and memory scores
improve as well.

Exercise improves cognition for two reasons:

Exercise increases oxygen flow into the brain, which reduces brain-bound free radicals. One of the most interesting findings of the past few decades is
that an increase in oxygen is always accompanied by an uptick in mental
sharpness.

Exercise acts directly on the molecular machinery of the brain itself. It increases
neurons’ creation, survival, and resistance to damage and stress.
